Removal of Methylene Blue From Aqueous Solutions Using Pine Cone and Statistical Comparison of Adsorbed Material

Abstract

In this study, pine cone, a previously unused biosorbent substance, was used to remove methylene blue from the aqueous solution. For this purpose, pine cones were first cut into pieces, then dried at room temperature, passed through a grinder, sieved in a 230 mesh sieve and brought to the appropriate dimensions and used in experimental processes. On pine cone and methylene blue biosorption; effects such as initial dye concentration, temperature, amount of biosorbent and equilibrium contact time were investigated. In the adsorption of methylene blue with pine cone, descriptive statistical analyzes and comparisons of time-dependent concentrations were made and the results were significant. Descriptive statistical analyzes and comparisons of the concentration were also made and it was seen that the adsorption did not varied depending on the temperature at different methylene blue concentrations.
